A detailed explanation of the care principles behind orchid leaf shape, to help you grow good leaf shape
This flower was collected in Bijie, Guizhou in earlier years. Because plain-heart orchids were cheap at the time, this flower was divided among several orchid friends to grow for fun, and later all of them died. Fortunately, fate favored this flower: the two small seedlings that President Yang Gang received at the time managed to keep this variety alive, and after several years of careful care, it finally recovered its vigor and bloomed many times. This year at the Bijie Cymbidium exhibition, President Yang...
In summer, with high temperatures and high humidity, you should avoid the midday sun; still give it some sun in the morning and evening, and at noon place it in a spot with strong scattered light.
The second factor affecting leaf length is fertilizer; you should use as little nitrogen fertilizer as possible and use more compound fertilizer with high phosphorus and potassium content.
The height of the plant is also greatly affected by temperature difference and air humidity. Spring seedlings, because of the large temperature difference and low humidity, generally have more leaves and shorter ones, while summer seedlings, because of the small temperature difference and high humidity, generally have fewer leaves and longer ones.
This way you can distinguish balcony orchids from greenhouse orchids. Knowing this principle also lets you tell them apart: the plant shape of a pot of greenhouse orchids is all about the same, while balcony orchids are different!
